ABSTRACT
The aim of current research was to evaluate the ecotoxic effect of four Amazonian plants of ethnobotanical importance in Pucallpa, Peru Dutchmans Pipe Aristolochia pilosa Kunth (Aristolochiaceae) in stem and leaves, Soapberry Paullinia clavigera Simpson (Sapindaceae) in cortex, Wandering Jew Tradescantia zebrina Hort ex Bosse (Commelinaceae) in all plant and Curare Chondrodendron tomentosum Ruiz & Pavon corr. Miers (Menispermaceae) in cortex and leaves on first instars insect larvae of Chironomus calligraphus Goeldi 1905 and second instars nauplii of brine shrimp Artemia franciscana Kellog, 1906. Standard procedures were employed to detect semiqualitative phytochemistry of hexane, chloroform and hydroalcohol extracts, for each plant evaluated. The LC50 mean values of hexane and chloroform extracts of all plants on A. franciscana and hydroalcoholic extract on C. calligraphus were lower than values of chloroform extracts on C. calligraphus. Leaves hexane extract and stem chloroform extract of A. pilosa, and hydroalcohol extract of P. clavigera had higher activity on C. calligraphus. However, hexane and chloroform extracts of T. zebrina, and stem hydroalcoholic extract of A. pilosa had higher activity on A. franciscana.
RESUMEN
El objetivo del presente trabajo fue evaluar el efecto ecotoxico de cuatro plantas amazónicas de importancia etnobotánica en Pucallpa, Perú Huancahuisacha Aristolochia pilosa Kunth (Aristolochiaceae) en talloy hoja, Sacha Yoco Paullinia clavigera Simpson (Sapindaceae) en corteza, Oreja de Tigre Tradescantia zebrina Hort ex Bosse (Commelinaceae) toda la planta y Curare Chondrodendron tomentosum Ruiz & Pavon corr. Miers (Menispermaceae) en corteza y hoja sobre las larvas de primer estadio de Chironomus calligraphus Goeldi 1905 y sobre los nauplios de segundo estadio del camarón salino Artemia franciscana Kellog, 1906. Se emplearon procedimientos estándares para la detección fitoquímica semicualitativa de los extractos hexánicos, clorofórmicos e hidroalcohólicos de las plantas evaluadas...
